4.3.2. Leakage current measurement on Single phase system
CAUTION
Do not perform any AC current measurement on circuit with nominal voltage
higher to 500V to round to avoid possible electrical shocks and to damage
the meter
Fig. 4: Taking leakage current measurement on Single phase systems
1. Select the
300mA
range on the meter
2. Move the
FILTER
selector on ON position to activate the “Low-pass 150Hz filter” (see §
4.2.3)
3. Open the clamp and put inside:
¾
The cables L1 and N if use the
Differential
method as shown in
¾
Fig.
4
obtaining the result as addition of instantaneous values of the currents flowing
in the wires
¾
The PE conductor if use the
Direct
method
4. The measured result is shown at display
5. For using of Data HOLD and see § 4.2.2. For using of analogical output see § 4.2.6
